an easy one - Image selection box

Adjust the page indicators so that they are larger and have page numbers in them.

Add an activated page indicator.

Harder options for image selection box:

Ultimately, if “add image” function was a pop-out box you could drag-and-drop new images on, then this would create less hassle when adding multiple images or trying to return to where you were last in the image viewer.

Adding zoom-in and zoom-out functions would allow users to make the images more visible. ( guess I could always use my control zoom on my mac haha)

Thanks for adding the grid lines, maybe next would be the automatic adjusting grid lines you see in Keynote on the Mac. :)
